The invention discloses a terminal guidance shell demonstrating system which belongs to a demonstrating system. The terminal guidance shell demonstrating system comprises the components of a sand table part which is controlled by a control circuit and is zoomed according to a real condition according to the same proportion, a demonstrating board part and a simulated shell body part. The demonstrating board part comprises a work process area and an LED trajectory display area. The LED trajectory display area comprises two trajectories which represent a far area and a near area. Each trajectorycomprises different flight trajectory segments which are represented by light emitting diodes with different colors. The simulated shell body part comprises a simulated shell body for simulating the trajectory flight motion. A controller controls the simulated shell body part to simulate the typical action in a flight process, a work process of the work process area, a flight segment of the LED trajectory display area and the action process of partial weapon systems of the sand table part and perform synchronous displaying. The terminal guidance shell demonstrating system dynamically present teaching contents such as weapon system position configuration, terminal guidance shell action process, typical actions in trajectory flight and far-area and near-area trajectory forms, and furthermoreimproves an actual teaching effect.
